UNITED STATES PATENT OFFICE.

JOSEPH EBB, OF COLUMBUS, OHIO.

PRISON.

SPECIFICATION forming part of Letters Patent No. 344,644, dated June 29,1886.

Application filed April 22, 1886. Serial No. 199,770. (No model.)

To all whom it may concern.-

Be itknown that I, JosEPH ERB,-a citizen of the United States, residingat Columbus, in the county of Franklin and State of Ohio, have inventednew and useful Improvements in Construction of Prisons, of which thefollowing is a full and exact description, reference being had to theaccompanying drawings, making part of this specification.

My invention relates to an improvement in the construction of prisons,and has for its objects to procure the perfect isolation of theprisoners, and to prevent them from talking to those in the adjacentcells; to confine bad odors to one cell, instead of allowing them tocirculate throughout the whole prison, and to prevent the spreading ofdisease; to prevent the waste of heat by cutting off that portion of theprison not in use, and to procure perfect ventilation.

Prisons as heretofore constructed have been provided with corridorsbetween the windows and cells, the light being introduced into the cellsthrough bars facing the windows. In this passage is a watchman, who cansee from one end of the prison to the other, and'can thus prevent escapebeyond the passage. The difficulty with this method is that theprisoners can hold conversation through the bars and conspire for someconcerted action. By this means bad odors and pestilential diseases maybe transmitted from one cell throughout the prison, or atleast thatsection of the prison in which the foul cell is. By this means the heathas to begreat enough to heat the whole section, when only a small partis occupied.

In the accompanying drawings, which illustrate my invention, Figure l isa plan view of a section of a prison provided with my invention. Fig. 2is a section of the same.

A is the center corridor of the prison, into which the cells 0 open bymeans of the door F.

B B are the corridors between the cells C O and the windows G G.

O G are the cells provided with solid partitions and door F. At the rearof cells 0 O are gratings E E.

D D are doors in the corridors B B, between each cell. They are providedwith clear glass panels d d.

G G are barred windows of the ordinary construction.

H H are water-closet hoppers,placed against the grating for convenienceof cleaning without coming in contact with the prisoner.

I I are ventilating-shafts, placed so as to conduct the foul air fromeach cell separately.

K K are steam-coils for heating, and are 'placed in the corridor B, outof reach of the prisoner.

By means of the door D the prisoner is perfectly isolated from hisneighbors, while the purpose of the corridor is still preserved, as thewatchman can still see from one end of the corridor to the other throughthe glass paneling d,- the bad odors and diseases are in a great measureprevented from spreading; the heat is preserved for only the occupiedcells, and by means of the ventilatingshaft in each cell a perfectVentilation is secured.

Having thus described myinvenlion, what I claim is- 1. The constructionof prisons or other places of confinement provided with corridorsbetween the windows and cells, with par titions in said corridorsbetween the said cells, provided with doors having transparent panels,substantially as set forth.

2. The construction of prisons or other places of confinement providedwith corridors between the windows and cells, with partitionsin saidcorridors between the said cells, provided with doors having transparentpanels, and heating apparatus between each two of said partitions,substantially as set forth.

3. The construction of prisons or other places of confinement providedwith corridors between thewindows and cells, with partitions in saidcorridors between the said cells, provided with doors having transparentpanels, with heating apparatus and a ventilatingshaft between each twoof said partitions, substantially as set forth. a

In testimony whereof I have hereunto set my hand this 19th day of April,A. D. 1886.

JOSEPH EBB.
